Embodiment Construction

[0017] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0018] Please refer to Figure 1 to Figure 4 , the invention provides a method for drilling ultra-long circuit boards, comprising:

[0019] Step 1, such as figure 2 As shown, the first positioning hole 2, the second positioning hole 3, the third positioning hole 4 and the fourth positioning hole 5 required for drilling are drilled on the circuit board 1 using an X-ray target machine. The circuit board 1 includes an effective pattern area 6. The first positioning hole 2, the second positioning hole 3, the third positioning hole 4 and the fourth positioning hole 5 are set corresponding to the four sides of the circuit board 1 and located outside the effective graphic area 6, and the first positioning hole 2 It is set opposite to the third positioni...

Abstract

A boring processing method of a super-long circuit board comprises the steps of: 1, forming a first positioning hole, a second positioning hole, a third positioning hole and a fourth positioning hole, which are needed by boring, in the circuit board by using an X ray target-shooting machine, wherein the first positioning hole and the third positioning hole are opposite to each other, and the second positioning hole and the fourth positioning hole are opposite to each other; 2, utilizing the first positioning hole, the second positioning hole and the fourth positioning hole to fix the circuit board to a processing bench of a boring machine, and utilizing a first shaft of the boring machine to machine a region which is arranged on a connecting line between the second positioning hole and the fourth positioning hole and is close to the side of the first positioning hole; and 3, utilizing the second positioning hole, the third positioning hole and the fourth positioning hole to fixed to the circuit board to the processing bench, and utilizing a second shaft of the boring machine to machine a region which is arranged on a connecting line between the second positioning hole and the fourth positioning hole and is close to the side of the third positioning hole. The method can be adopted by a common boring machine to machine the super-long board, the production efficiency is improved, and the equipment cost is lowered.

Description

technical field [0001] The invention relates to the field of circuit board processing, in particular to a drilling and processing method for an ultra-long circuit board. Background technique [0002] In the PCB industry, boards longer than 24 inches are called ultra-long boards. Generally, when small companies encounter this kind of super long board, they directly reject the order, because they are unable to meet customer requirements in terms of CNC drilling. For some large companies, machines with large processing tables are generally used for production, which virtually increases production costs. The present invention adopts two segmental processing and uses a common positioning hole to manufacture, which completely solves the problems of large size and difficult processing. [0003] Large-size backplanes are the future direction of the PCB industry, but many companies in the industry cannot meet or have no way to solve the processing and production requirements of suc...
